A while back I purchased an obd1 setup from a H-T member.

I am going to run:
P30-A00 ecu (tested, and functioning OK)
PR3 dizzy (new)
Boomslang harness
OBD0 injectors (in car, running fine)
4 wire 02 sensor (using them on my obd-0 setup without issues)

So when I follow all the instructions, hook up the dizzy, ecu and such...I start the car.

This is where the problems start.
It starts looking for an idle point it seems. It's not really surging...but bouncing really irratic.
It throws a solid CEL at me. So I can't even read my codes.

I tried the ECU in another car. It works.
Trouble is... the ECU is fully loaded with all possible options.
Knock, ELD, Injector test cirquit... nono of wich I am using on my car. I was under the impression I could use the ECU without those things.
And if so... would these throw a solid CEL?
Do I need to chip my ECU and turn all those things off to get it to work?

Might there be a problem with my harness?
I am currently back at running my OBD0 PW0 ecu.
Could it be that the EDM and USDM PW0 pinout is different? I can't find a pinout in my service manual.
... anybody have inside knowledge? This is pissing me off... Wanna be obd1 before I install my head package.

 

If the ecu worked in another car, I would start looking at other things in that harness or your setup.

 

Problem is... that integra is an obd2>obd1 converted car. It already has all those extra sensors in the car. I know the ECU is not broken...but I don't know if I could get it to work in my setup.
I was expecting a code for the knock, and for the o2 sensor that I still had in the wrong spot...but instead I get a solid CEL.

As it turns out, I have a (very) old boomslang harness. I am returning it, and he is converting it to the newest version with some sort of sub harness on it. I'm not entirely sure what that does yet... but I'm going to take him up on his offer. Can't hurt to have it double checked to rule out a faulty harness.

Can anyone confirm, or debunk the rumour that EDM wiring is different on the B16/PW0 ?
